DO NOT exceed the maximum platform capacity. The weight of options and
accessories will reduce the rated platform capacity and must be factored into the
total platform load. Refer to the decals on the options.
DO NOT elevate the platform when the machine is on a surface that is soft
and / or on a slope.
DO NOT depend on the tilt alarm as a level indicator.
STOP if the tilt alarm sounds and the red light illuminates when the platform is
raised. Use extreme caution to lower the platform. Move the machine to a rm,
level surface.
Driving: DO NOT drive the machine on a slope that exceeds
the maximum uphill or downhill slope rating. Slope rating applies to machines in
